In the early
1950's Kollmorgen Inland Motor, in cooperation with MIT, developed
the original torque motor. Over the years, Kollmorgen has designed
torque motors for applications from missiles to machine tools,
injection molding machines, and semiconductor processing machines.
With new motor designs, parts for these older motors are becoming
more difficult to obtain.
